In a moving picture data structure having a structure comprising I pictures (intraframe coded image) and P pictures (interframe forward predictive coded image), a P′ picture of a forward predictive coded image of a picture immediately preceding an I picture and the I picture is placed following the I picture. If an error occurs during the I picture transmission, the P′ picture can be used to recover from the error.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A moving picture reception apparatus which receives moving picture data, comprising: a display for displaying a moving picture based on received moving picture data; and a network interface through which the moving picture data is transmitted, wherein the moving picture data has a structure comprising: I pictures (intraframe coded image); P pictures (interframe forward predictive coded image); and P′ picture which is a forward predictive coded image of a picture immediately preceding an I picture and the I picture, wherein said P′ picture is placed preceding or following the I picture.
2. A moving picture transmission apparatus which transmits moving picture data comprising: a data transmitter for transmitting the moving picture data; and a network interface through which the moving picture data is transmitted, wherein the moving picture data is transmitted to a moving picture reception apparatus that displays a moving picture based on the moving picture data, and wherein the moving picture data has a structure comprising: I pictures (intraframe coded image); P pictures (interframe forward predictive coded image); and P′ picture which is a forward predictive coded image of a picture immediately preceding an I picture and the I picture, wherein said P′ picture is placed preceding or following the I picture.
3. A moving picture reception apparatus which receives moving picture data, comprising: a display for displaying a moving picture based on received moving picture data; and a network interface through which the moving picture data is transmitted, wherein the moving picture data has a structure comprising: I pictures (interframe coded image); P pictures (interframe forward predictive coded image); and P″ picture which is a forward predictive coded image of an I picture immediately preceding the current I picture and the current I picture, wherein the P″ is placed preceding or following the current I picture.
4. A moving picture transmission apparatus which transmits moving picture data comprising: a data transmitter for transmitting the moving picture data; and a network interface through which the moving picture data is transmitted, wherein the moving picture data is transmitted to a moving picture reception apparatus that displays a moving picture based on the moving picture data, and wherein the moving picture data has a structure comprising: I pictures (interframe coded image); P pictures (interframe forward predictive coded image); and P″ picture which is a forward predictive coded image of an I picture immediately preceding the current I picture and the current I picture, wherein the P″ is placed preceding or following the current I picture.
